If you would like to install the most commonly used extensions for PHP 8.2, use the following command:

sudo dnf install php-cli php-fpm php-curl php-mysqlnd php-gd php-opcache php-zip php-intl php-common php-bcmath php-imap php-imagick php-xmlrpc php-json php-readline php-memcached php-redis php-mbstring php-apcu php-xml php-dom php-redis php-memcached php-memcache

Configure PHP-FPM Service

By default on Rocky Linux 8, the PHP-FPM service is designed to be run by (Apache) user. If you are using Nginx you need to make configuration changes at (www.conf).

You can open the file with your favorite text editor, here we use vi:

sudo vi /etc/php-fpm.d/www.conf

Find the user and group directives and change them to Nginx as shown below:

user = nginx
group = nginx

When you are done, save and close the file.

Reload the PHP-FPM service to apply the changes:

sudo systemctl restart php-fpm

The Nginx server block needs the following example below for Nginx to process the PHP files.

Below is an example for all server {} blocks that process PHP files that need the location ~ .php$ added.

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/run/php-fpm/www.sock;
        fastcgi_index   index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
